Not sure how this got here. I meant for it to be in General. If it could be moved, that would be great.

Our Series is a bit weird in that we've never had an affinity for SCCA classing, having operated with our own classing system for over a decade now. Our event sizes are just too small (80 to 90) to support SCCA's granularity and the course layouts permitted by our venue are too small and tight to map well against the the datasets that drive PAX values.

Our system has served us well over the years, providing a number of benefits:

easy to access and understand for beginners who just want to give it a shot

doesn't force a rigid upgrade path, recognizing that cars are being built for multiple purposes (track, hardparking, etc.)

small number of well-populated classes with solid competition

Another Ontari0-based group using AxTime, began using a tailored version of our approach in 2016 and I believe they were happy with it.

This year, our system underwent its biggest change in a long time as we changed how we put cars in base classes. The change was spurred by a desire to further reduce the exercise of judgement by us (SCCA obviously still does its thing).

If you're interested, you can check it out on our rules page, here. Background can also be found off our Autocross News page.

Last year, our club adopted an MCO based 'mod points' system and it was our most successful year yet!

We had the same concerns from our members that SCCA classing didn't suit our needs due to smaller club size and smaller lots. We get between 20-35 drivers per event and wanted something easy to use and understand..... Enter the MCO system!

Their system uses 5 pre-dertermined base classes - your car's SCCA Street class will determine what MCO base class you start in. Then from there, as you mod your vehicle, modification points are accrued. Every 15 points gets you bumped up a class.

What we did to modify the system for our club was:

We determined which SCCA Street classes would fall into 3 Thunder Bay Autosport Club base classes.

We had to account for MCO having 5 classes. We felt our club numbers could support only 3 classes at this time. We crunched numbers and determined that a 3 class/25 point bump would keep the same ratio as MCO's 5 class/15 point bump.

The number of points assigned to each mod on MCO's car classing sheet was kept relatively the same. With us having only 3 classes to advance through vs their 5, this allows our drivers extra room to mod their vehicle before being bumped up a class and stops you from reaching the top class (A class) too quickly.

Finally, we determined which mods on MCO's classing work sheet were our system's deal breakers and gave the largest competitive advantage (tires & weigh reduction) and upped those points according to the same ratio as MCO (ie. assigning our full 25 mod points to sticky tires so this mod initiates an automatic jump and forces you up a class).

I recommend giving the MCO system a look, it's fun, fair, simple and new-user-friendly. If you have any questions, Naresh has been a great help while we figured our system out and of course I am also happy to answer any questions if able.
